What is true about melanomas in the eyes of cats and dogs? Dogs: commonly ❌, involving the ❌ and peripheral iris, eventually cause ❌ Cats: usually ❌, should always remove, need to differentiate from ❌, secondary glaucoma possible
Primary glaucoma - - Closed primary glaucoma: ○ Defect in the when it ends up being closed ○ Bilaterally but usually one first so act quick to save at least one eye ○ Many breeds effected. - Open angle glaucoma ○ Terriers and bassets ○ Rarer Lack of .
Ø More subtle (like feline uveitis) Ø Scleral congestion will be present Ø Rarely primary ex Burmese. Ø Corneal oedema is rare Ø Don't show pain as much.

Fill in the blanks for the treatment of different presentation of lens lauxation If behind pupil = If full luxated through pupil = or return to the posterior chamber. Need to treat secondary .
Causes of proptosis: - ❌- younger dogs, acute, painful opening mouth adn may see on US. - ❌- older dog, only usually painful if infected. ❌ - young dog, acute, all masticatory muscles and often bilateral.
This is ............. It occurs as the ......... densely pack the .......... Vision is/is not greatly affected
○ <15% lens volume ○ >15% but less than 100% ○ = 100% of the lens volume and there is loss of retinal reflex (PLR) and menance. = opacity shrink and lens fibres resorbed.
